Methoxychlor (MXC), an organochlorine pesticide, and its metabolites, mono-hydroxy MXC (MOH) and bis-hydroxy MXC (HPTE) are known ovarian toxicants and can cause inhibition of antral follicle growth. Since these chemicals bind to estrogen receptor alpha (ESR1), we hypothesized that ovaries overexpressing ESR1 (ESR1 OE) would be more susceptible to toxicity induced by MXC and its metabolites bec...

Anti-Müllerian hormone (AMH) is a member of the transforming growth factor-beta superfamily, which plays an important role in both ovarian primordial follicle recruitment and dominant follicle selection in mice. However, the role of AMH in folliculogenesis in humans has not been investigated in detail. In the present study, AMH expression was assessed using immunohistochemistry in ovarian secti...

BACKGROUND An alginate-based matrix supports the three-dimensional (3D) architecture of non-human primate follicles and, in the presence of FSH, permits the in vitro development of pre-antral follicles to the small antral stage, including the production of ovarian steroids and paracrine factors. The current study investigated the ability of gonadotrophins, fetuin and oxygen (O₂) to improve prim...

A variety of procedures to isolate intact pre-antral follicles have been developed in our laboratories based on different concentrations of collagenase and DNase in a simple salt solution containing glucose as an energy substrate. The enzyme mixture effectively separates follicles of different sizes derived from ovaries of hamster, mouse, rat, pig and human. While no damage of the basal lamina ...

The predominant pattern of follicle development in pigs is characterized by continuous activation, slow growth to the antral stage, and rapid growth to 4 to 5 mm followed by atresia. The only time that this pattern is broken is when a small portion of the follicle population is selected for ovulation. The mechanisms that regulate the selection of ovulatory follicles are not well understood. How...

INTRODUCTION In 2006, the World Health Organization launched the Global Age-Friendly Cities Project to support active aging. Canada has a large number of age-friendly initiatives; however, little is known about the effectiveness and outcomes of age-friendly community (AFC) initiatives. In addition, stakeholders report that they lack the capacity and tools to develop and conduct evaluations of t...

Aim To assess ovarian reserve (OVR) by means of follicle-stimulating hormone (FSH), anti-Müllerian hormone (AMH), and antral follicle count (AFC) measurement in eumenorrheic women with breast cancer, exposed to gonadotoxic chemotherapy. Method Fifty-two women (35.3 ± 3.8 years old) with breast cancer and undergoing cyclophosphamide-containing chemotherapy were enrolled. The assessment was perfo...

OBJECTIVE This study aimed to identify factors that affect in vitro fertilization (IVF) outcomes in women with diminished ovarian reserve (DOR). METHODS We reviewed 99 IVF cycles in 52 women with DOR between September 2010 and January 2015. DOR was defined as serum anti-Müllerian hormone level of <1.1 ng/dL or serum follicle-stimulating hormone level of ≥20 mIU/mL. Total 96 cycles in 50 patie...
